Application inea November 1 19192915 "ser'iai branca-ais@ This inventionrelates to a runwaycon# struction for seaplanes" and airplanes of theamphibian type.

It is an object of the invention to provide v [5; a construction orlmeans whereby such planes maybe quickly launched or'broug'ht out of thewater and in addition to provide a construction wherein theV timerequired for ini Stallation is reduced-'to a minimum.

Another object is to provide a noveljconstruction wherein maximum use-is made of pre-cast and pre-built units to be used, the

construction enabling most of the assembly ofthe apparatus to take placeout of the water 16 be accomplished by sliding movement.

Another object is to'provide a novel construction which is ofknock-downtype.l

Various additional objects and advantages will become apparent from aconsideration of the description following taken in connection withaccompanying drawings` illustrating an operative embodiment.

In said drawings Y Figurel is a planview of a runway constructed inaccordance with my invention,

A modiied form of the invention is shown inFigures 5 and 6. The onlydiiii'erence is in the cap which here is designed 15L and istheequivalent of the cap 15. 4Such cap 15EL if` desired may be made ofconcrete and in its lower surface it may have a recessV 30 into whichthe upper lends ofthe piles extend. f In addition the caps 15a haveslotsl'intoq v Y which thek shackles pass.

A further modified form isgshown in Fig-` ures 7 and 8 and thedifference over the form of Figures 1 and Qresiding in jomitting'plates18 so that theslabs 22'Vwill rest on the upper surface of beams 16.
